TadaMark 30 Series Torque Converter Driven Pulley — 6" Diameter, 5/8" Bore for 2–7HP Engines, Iron Construction

The TadaMark 30 Series torque converter driven pulley is a 6" diameter, 5/8" bore clutch designed to replace Comet 219456A/217610A/219457A for 2–7HP mini bikes, go-karts and lawnmowers.

This heavy-duty driven pulley from TadaMark upgrades belt-drive systems with a compact, iron construction built to handle light engines up to 7HP. It’s intended as a direct-fit replacement for common Comet part numbers and is engineered to deliver dependable torque transfer, improved heat dissipation, and long service life when installed and broken in correctly. Read on to confirm fit, installation notes, and which machines benefit most from this unit.

Will this torque converter fit my machine?

The pulley fits driven shafts with a 5/8" bore and has an outside diameter of 6". It is specified for small engine applications from approximately 2HP to 7HP and replaces Comet part numbers 219456A, 217610A, and 219457A. Check your existing clutch for matching bore, diameter, and bolt pattern before ordering.

• Driven shaft bore: 5/8" (0.625 inch)
• Outer diameter: 6 inches
• Compatible with engines rated roughly 2–7HP
• Direct replacement for Comet 219456A, 217610A, 219457A

How do I install and break in this driven clutch?

Installation follows the same steps as most single-stage driven pulleys: remove the old unit, confirm shaft and key alignment, slide the TadaMark clutch onto the shaft, and secure to factory torque specs. The manufacturer recommends a brief break-in of 3–5 short runs to ensure the clutch shoes bed in evenly and establish proper contact without excessive slippage.

• Clean shaft and keyway, remove rust or debris before fitting
• Tighten mounting hardware to your engine or adapter spec
• Perform 3–5 short run cycles for break-in to avoid smoke or slippage
• If initial speed is low, continue controlled break-in to increase contact area

What materials and durability features does this pulley offer?

The TadaMark driven pulley is made from high-quality iron for strength while keeping overall weight moderate for responsive operation. Its design prioritizes heat dissipation and wear resistance so the clutch maintains performance under repeated load cycles typical of yard and recreational equipment.

• Iron construction for structural strength
• Engineered for rapid heat dissipation during use
• Wear-resistant surfaces to extend service life
• Lightweight for reduced rotating inertia

What should I expect after installation regarding performance and maintenance?

Once installed and broken in, expect improved belt-driven torque transfer and consistent engagement for low- to mid-range engine loads. Routine checks of mounting tightness and occasional inspection for wear or overheating will keep the unit functioning well; replace if excessive wear or damage appears.

• Stable engagement after proper break-in
• Monitor for unusual noise, smoke, or slipping during first uses
• Periodic inspection for wear and secure fastenings advised
• Contact seller if product shows installation or function issues

Who is this for: The TadaMark 30 Series 6" driven clutch suits hobbyists, landscapers, and small-engine repairers who need a reliable Comet-compatible replacement for mini bikes, go-karts, lawnmowers and other light machinery running 2–7HP engines. It’s ideal when you require a straightforward drop-in part with robust iron construction and clear break-in guidance to restore belt-drive performance.
